COLOR-PRINTING PRESS.

SPECIFICATION forming part of Letters Fat ent No. 606,891, dated July 5,1898.

Application filed January 26, 1895. Serial No. 536,837. (No model.)

To all whom it may concern:

Be it known that I, SIDNEY KLoTZ, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented certain newand useful Improvements in Processes of and Presses for Printing in Twoor More Colors, of which the following is a specification.

The object of my invention is to provide a simple, economical, andefficient process and press that will print a circular, letter,billhead, or other matter in two or more different colors at oneoperation and theinvention consists in the features and combinationshereinafter described and claimed.

In the accompanying drawings, Figure 1 is a transverse sectionalelevation of a platen printing -press with my improvements attachedthereto, taken on line 1 of Fig. 2; Fig. 2, a front sectional elevationtaken on the irregular line 2 of Fig. 1; Fig. 8, an enlarged sideelevation of the upper portion of my machine, as hereinafter describedFig. 4, a perspective detail View of one of the cams; and Fig. 5, anenlarged view of the cams and the means of attachment to the machine,taken on line 5 of Fig. 3, looking in the direction of the arrow.

In the art of printing it is often desirable to print circulars,postals, letter-heads, billheads, lithographs, due, in two or morecolors for the purpose of ornamentation or to attract attention toparticular portions of the advertisements or bill-heads, dvc. To do thisitis usually necessary to run such matter through the press a number oftimes, corresponding to the number of colors desiredto be used. This isvery expensive in that the cost of handling and rehandling the materialso many times is largely in excess of the actual time taken in making animpression. Various expedients have been used to overcome this objectionand print in several colors at one operation, among which is theapplying of several colors to one disk, so that the inking-rollswilltake up the different colors and divide them in theirlongitudinallength. The type is set lengthwiseof the motion of therolls, so that the colors are applied to them in the same relation thatthey are distributed on the disk. The objection to this mode or processis that if the type be set lengthwise of the motion of the inking-rollsthe rolls will be rapidly worn away rendering them unfit for use in thatthey become grooved or cut and do not spread the ink evenly. Theapplication of different colors to one line of type by the above methoddoes not present an ornate appearance nor bring out the featuresdesired. To overcome these objections and provide a simple andeconomical printing press bywhich any number of colors may be applied tosuccessive or alternating lines of type and an impression takentherefrom at one operation is the principal object of my invention.

In the drawings I have shown my improvements applied to an ordinaryprinting-press of the platen type, in which the bed is sta tionary andthe platen oscillated into parallelism with the bed that holds the formto make the desired impression upon the paper. I will not enter into anydetailed description of the ordinary parts of the press, as they are oldand will be readily understood by those skilled in the art, as thedrawings clearly show the parts to enable any mechanic or person skilledin the art to understand the Same.

V

From this short description and an examination of the drawings theordinary opera tion of the parts will be readily understood.

It is desirable at times to print either successive or alternating linesof type in two or more colors. In order to accomplish this result, Iprovide the press with the inking-disks above described, and each diskis adapted to receive a separate color. These inking-disks or what Iterm in the claims broadly as plane rotating inking-surfaces arearranged in multiple relation with each other, or, which might be saidin other words, the inking-disks are arranged in different horizontalplanes, so that the ink is applied to the inking roll or rolls atpractically, or nearly so, the same period of time, all of which will beapparent from an inspection of Figs. 1 and 2 of the drawings and as theyare hereinafter described.

In this specification I will describe and show mechanism for printing inbut two colors; but it will be understood that when additional colorsare used a separate inking-disk is required for each additional color.

To further facilitate the description, I will assume that the disk Dbears the ordinary black color and the disk D a red color. To applythese colors at one operation to the proper line of type in the form andfrom that to the article to receive the impression, I provide theinking-rolls E and E above described, which are mounted in carriers andprovided with rollers e and 6, running in independent tracks E and E-that is, each roll has its separate pair of tracks upon which it runs,so that for the inking-roll E its track leads to the black-inking diskand for the inking-roll E its tracks lead to the red-inking disk. Duringthe operation of the machine, therefore, these rolls are led to theirrespective disks, and the springs upon their carrier-arms keep themnormally in engagement with the tracks. To apply the ink from thesedisks by means of the inking-rolls to the proper line of type, I preferto make the tracks normally level and parallel with the surface of thechase, so that as the inking-rolls move along upon the tracks they willnormally contact the face of the type and ink the same. lVhere it isdesired to apply the ink of the respective roll-as, for instance, fromthe black-inking rollthe track is left free, and, as shown in Fig. 2 ofthe drawings, it would contact the line of type 1. It is desirable,however, that it should not contact line 2 or 4, as for these lines oftype it is desired to apply the red ink. In order to accomplish thisresult, I provide cams G and place them on the track in the same line oropposite the type to be skipped, securing them thereto in any suitablemanner, preferably by means of the bolt and nut g. (Shown in Fig. 5.) Asthe black-inking roll therefore travels along its track it will contactthese cams and be raised above the type in alinement therewith, todescend again in the free space 9 and ink line 3, rising again oppositeline of type 4 to prevent contact with such line. In the case of thered-inking roll similar cams G are placed. opposite the lines of type 1and 3 of the form, so that the inkingroll is thereby raised fromcontacting such line, but permitted to descend and contact the trackwhere it is free, or opposite lines 2 and 4, and in position to ink suchlines. It will therefore be seen that both inking-rolls, which arecarried along simultaneously in one operation, apply the proper color ofink to the alternating lines of type-that is, lines 1 and 3 are inked inblack and lines 2 and 4 in red, so that when the oscillating platen,with the article to be printed, comes in contact with the form thearticle will receive the impression in the colors so disposed.

For the sake of simplicity I have described but one inking-roll for eachcolor; but it will be understood that several rolls are generally usedand that I can use them with very slight modifications. With regard toinking successive lines of type with similar colors the cams which areplaced upon the roll-tracks may be of anylength or size, so that theymay present a raised plane opposite the successive lines of type that itis desired to skip for one roll, leaving a space free where they are todescend and contact the desired lines of type. Supposing it is lines 1and 2 of the form that it is desired to ink in black and lines 3 and 4in red, the cam G is made large enough to present a raised planeopposite lines 1 and 2, leaving the track-surface free opposite lines 3and 4, while on the track for the black-inking roll cams G would beplaced in position to present a raised plane opposite lines 3 and 4. Asboth inking-rolls descend from the inking-disks the black ink will bespread on lines 1 and 2 and the red ink on lines 3 and 4.

My second rotating inking-disk D, with its track, by which thechromoprinting is actually provided, is made in the form of a chromaticprinting attachment and consists of the upper ink-table D, which isarranged parallel to the ordinary table D and is removably attached tothe press parallel with the ordinary inking-table by means of the tracksE, which form, as it were, a supporting-bracket held in place by meansof the bolt E The second set of form-rolls E are mounted upon the shaft6 relatively movable when compared with the shaft upon which theordinary form-rollers are mounted, such shafts having wheels 6 e, whichrun upon the tracks E E and by which the rollers are run and raised intoand out of contact with the proper inktables and lines of type.

The operation of this platen printing-press above described with thetype set as illustrated in Fig. 2 of the drawings would be as follows,assuming a circular to be printed: The circular to be printed would beplaced upon the oscillating platen and the type in the form inked duringthe passage of the inking-rolls across the same, so that black ink wouldbe applied to lines 1 and 3 and red ink to lines 2 and 4. The operationof the press would bring the platen and its blank circular intoparallelism with the form to receive the impression. Its rearwardoscillation away from the form during the operation of the machine wouldbring the inking-rolls up and over the type,reinking the same,and up incontact with the respective inking-disks. These operations would becontinued until the desired number of circulars were printed, and eachcircular would be printed in two colors in one operation without thepossibility of mixing the colors or causing more than ordinary wear tothe parts.

While I have described my improvements with more or less minuteness asregards details and as being embodied in precise forms, I do not desireto be limited thereto unduly any more than is pointed out in the claims.On the contrary, I contemplate all proper changes in form, construction,and arrangement, the omission of parts and substitution of equivalents,as circumstances may suggest or necessity render expedient.
